Study on slope stability in Xiamen Sandaogou building stone open-pit mine
YAN Dongjin
Abstract：In order to study the stability of final slopes of Sandougou building stone open-pit mine in Xiamen Township,based on the existing geological conditions and rock mechanical parameters,the study selects typical profiles under three different working conditions to discuss the stability of the open-pit final slopes of the mine by FLAC3D software;the study determines the safety coefficient of the slope,the distribution characteristics of the plastic zone,and the distribution characteristics of the shear-plastic strain.The study results reveal that the plastic zone exists only locally on the slope face of the mine side slope,and does not form a wide range of penetration;the shear plastic strain increment is mainly distributed in the shallow surface layer of the slope face of the south side slope,and does not form a slip zone in the deeper part of the slope face;the final slopes of the mine remains generally stable.
